Discovery of a most remarkable cave-specialized trechine beetle from southern China (Coleoptera, Carabidae, Trechinae).

ABSTRACT: Xuedytes bellus Tian & Huang, gen. et sp. n. is described from a limestone cave in Du'an Karst of Guangxi, a kingdom of cavernicolous trechine beetles in southern China. From a morphological point of view, Xuedytes Tian & Huang, gen. n. seems to be the most extremely cave-adapted trechines in the world. Superficially, it looks much like Giraffaphaenops Deuve, 2002 in general body shape, in particular the structure of the prothorax, but simultaneously it is similar to Dongodytes (s. str.) Deuve, 1993, based on elytral characters, including chaetotaxy. Hence the new genus seems to represent a lineage intermediate between Giraffaphaenops and Dongodytes (s. str.).

First cavernicolous trechine beetle discovered in Guilin karst, northeastern Guangxi (Coleoptera, Carabidae, Trechinae).

Project description:A new subgenus and new species of anophthalmic trechine beetles, Oodinotrechus (Pingleotrechus) yinae subgen. n., sp. n., is described and illustrated from a limestone cave called Chaotianyan in southern part of Guilin karst, northeastern Guangxi Zhuang Autonomous Region. The new taxon is very different from the Maolan-Mulun congeners belonging to the nominate subgenus Oodinotrechus (s. str.) Uéno, 1998, in several important character states including pronotal structure, elytral chaetotaxy and male genitalia. It is the first record of a cavernicolous trechine beetle in Guilin karst, and in the eastern part of Guangxi. In addition, a distribution map for the genus Oodinotrechus Uéno, 1998, is provided.

Contributions to the knowledge of subterranean trechine beetles in southern China's karsts: five new genera (Insecta, Coleoptera, Carabidae, Trechinae).

Project description:Recent discoveries reveal that southern China's karsts hold the most diverse and morphologically modified subterranean trechine beetles in the world, albeit the first troglobitic blind beetle was only reported in the early 1990's. In total, 110 species belonging to 43 genera of cavernicolous trechines have hitherto been recorded from the karsts of southern China, including the following five new genera proposed below: Shiqianaphaenops Tian, gen. n., to contain two species: Shiqianaphaenops majusculus (Uéno, 1999) (= Shenaphaenops majusculus Uéno, 1999, comb. n.), the type species from Cave Feng Dong, Shiqian, Guizhou, and Shiqianaphaenops cursor (Uéno, 1999) (= Shenaphaenops cursor Uéno, 1999, comb. n.), from Cave Shenxian Dong, Shiqian, Guizhou; and the monotypic Dianotrechus Tian, gen. n. (the type species: Dianotrechus gueorguievi Tian, sp. n., from Cave Dashi Dong, Kunming, Yunnan), Tianeotrechus Tian & Tang, gen. n. (the type species: Tianeotrechus trisetosus Tian & Tang, sp. n., from Cave Bahao Dong, Tian'e County, Guangxi), Huoyanodytes Tian & Huang, gen. n. (the type species: Huoyanodytes tujiaphilus Tian & Huang, sp. n., from Longshan, Hunan) and Wanhuaphaenops Tian & Wang, gen. n. (the type species: Wanhuaphaenops zhangi Tian & Wang, sp. n., from Cave Songjia Dong, Chenzhou, Hunan).

Yalongaphaenops erwini gen. et sp. nov., the world's most high-altitude hypogean trechine beetle from China (Coleoptera, Carabidae, Trechinae).

Project description:A new genus and new species of carabid beetle, Yalongaphaenops erwini gen. et sp. nov., is described from mountains SW of Mianning City, Sichuan Province, China. This finding, from one side, extends the known distribution of Chinese hypogean trechines, and from another, it raises the upper limit of their vertical distribution to nearly 4000 m. Photographs of the habitus and major taxonomic characters, including the male genitalia, right mandible, and microsculpture patterns of the integument are supplied. The type locality of the new taxon is mapped. Yalongaphaenops gen. nov. shows some similarities with the genus Shiqianaphaenops Tian, 2016 from eastern Guizhou and the genus Boreaphaenops Uéno, 2002 described from Hubei, China. However, the direct relationships of the new genus remain unclear. Further new discoveries of hypogean trechines in Sichuan are necessary to evaluate possible variation of major characters in allied taxa. Although Y. erwini sp. nov. was collected at an elevation exceeding 3800 m a.s.l., it conforms to the upper limit of the forest zone being approximately on par with the vertical distribution of some high altitude hypogean trechine species in other parts of the globe.

A new remarkable subterranean beetle of the Rhodopes: Paralovricia gen. n. beroni sp. n. belonging to Lovriciina new subtribe (Coleoptera, Carabidae, Trechinae, Bembidiini).

Project description:Paralovriciagen. n.beronisp. n., belonging to the new subtribe Lovriciina, is described from two caves in the Western Rhodopes (Bulgaria): Kraypatnata peshtera, near Smilyan Village (Smolyan Municipality) and Snezhanka, near Peshtera Town (Peshtera Municipality). Three currently known genera, Lovricia Pretner, 1979, Neolovricia Lakota, Jalži? & Moravec, 2009 and Paralovriciagen. n. represent a monophyletic unit supported by important synapomorphies that allows to propose the establishment of the new subtribe Lovriciina, characterized by the following characters: last maxillary palpomeres very long and narrow, basal angles of pronotum without seta, elytra without discal setae, elytral umbilicate series of nine pores in which the main pores are the 2nd, 6th and 9th, apical recurrent striole absent and mesotibial apex expanded outward. Its systematic position within the subfamily Trechinae (sensu Lorenz 2005) is discussed and Lovriciina is placed near Anillina. Key to the genera of the subtribe is proposed. Distribution data and zoogeographical hypotheses are discussed.

Du'an Karst of Guangxi: a kingdom of the cavernicolous genus Dongodytes Deuve (Coleoptera, Carabidae, Trechinae).

Project description:Recent cave biodiversity surveys carried out in Du'an County and its adjacent areas of northwestern Guangxi, China, have revealed some exciting scientific findings. In a very limited area seven new species of the cavernicolous trechine genus Dongodytes Deuve, 1993 were found and are described: Dongodytes(s. str.)elongatussp. n., Dongodytes(s. str.)troglodytessp. n., Dongodytes(s. str.)lanisp. n., Dongodytes (Dongodytodes) brevipenissp. n., Dongodytes (Dongodytodes) jinzhuensissp. n., Dongodytes (Dongodytodes) inexpectatussp. n. and Dongodytes (Dongodytodes) yaophilussp. n. Diagnoses and notes on the genus, subgenera, and two known species in Du'an Karst, Dongodytes(s. str.)baxian Tian, 2011 and Dongodytes (Dongodytodes) deharvengi Tian, 2011, are also given. A key to subgenera and all species of Dongodytes is provided. To date, Dongodytes becomes one of the richest in species genera of subterranean carabid trechines in China with 12 species which are arranged into two subgenera. Dongodytes (s. str.) Deuve is composed of seven species, four of which from Du'an County, each of other three from Bama, Fengshan and Tian'e Counties, respectively. All species of the subgenus Dongodytodes Tian, 2011 are recorded from Du'an Karst. By having 10 species (nine Dongodytes and one Libotrechus Uéno, 1998), Du'an Karst holds the richest specific diversity of cavernicolous Trechinae in China. Dongodytes species are distributed in a very limited area of the river Hongshui He drainages in northwestern Guangxi, and the river acts as a natural barrier of Dongodytes dispersal at only a specific level. However, all members of Dongodytodes are recorded from the eastern or northern bank of Hongshui He.

Evolutionary conservation of phototransduction and clock gene expression in the cave beetle Ptomaphagus hirtus (Coleoptera, Leiodidae)

Project description:Caves are populated with a diverse fauna of highly adapted species that tend to exhibit a consistent suite of both regressive and constructive trait modifications. Because molecular studies of cave adaptation have largely concentrated on vertebrate models, our ability to recognize universalities in the genetic trajectories underlying cave adaptation remains limited. We have initiated efforts to elucidate the molecular evolution of the flightless small carrion beetle Ptomaphagus hirtus (Ptomaphagus hirtus), which represents one of the highly endemic signature inhabitants of the Mammoth Cave system of Kentucky. Ptomaphagus hirtus has been considered blind despite the presence of lateral eye rudiments. However, analysis of the Ptomaphagus hirtus adult head transcriptome by deep RNA sequencing reveals the conservation and expression of all essential insect phototransduction genes including a single long wavelength-sensitive opsin. Consistent with the preservation of visual ability, Ptomaphagus hirtus expresses all core members of the clock gene network and exhibits a similar degree of negative phototaxis as does a closely related flight-active species in light-dark choice assays. The structural reduction of the peripheral Ptomaphagus hirtus visual system is reflected by the lack of five eye pigmentation specific genes in the head transcriptome. Taken together our data suggest that wavelength contingent and probably also spatial vision have been lost in Ptomaphagus hirtus, while irradiance vision and contingent behavioral modules have remained preserved. We predict that the adaptive state of Ptomaphagus hirtus is representative for a large number of microphthalmic species adapted to the twilight zone of caves and other subterranean habitats
